secondMillis2=millis(A1)-x; doesn't work. plz tell me what's wrong with it

Tell us more.

Use CTRL T to format your code.
Attach your sketch between code tags
[code]Paste your sketch here[/code]

‘millis(A1)’
Check how you use the millis() function.

3 
 firstMillis1=millis(A0);

Right there.

Please remember to use code tags when posting code

ok. fixed the problem. thx

Not seeing that

andrewk1219:

   secondMillis2=millis(A1)-x;

doesn't work. plz tell me what's wrong with it

The function 'millis()' does not take an argument. What did you think putting 'A1' there would do?!?

Note: All of these:

   }else if(b<firstMillis1<c){

are broken. You have to use:

   }else if(b < firstMillis1 && firstMillis1 < c){

if(buttonstate=1) Also oops
